For the workload that I often run (FreeBSD "make world" :-) I seem
to remember about a 10% improvment when I switched one of my systems
from a 512KB half-speed cache (orig Athlon) to a 256KB full-speed
cache Thunderbird where the processor speed was the same.  I certainly
wouldn't argue that a different job mix could produce a different or
even the opposite result, it's just that it appears that "make world"
isn't one of them.  Note that this was all that the system was doing at
the time.
